SUBCLASSING CONFIRMED IN ESO
What we know (pre-PTS)
You need to be level 50 to unlock it
Skills cost 2 skill points instead of 1, and level slower
Leveling progress is saved account wide
You must have access to the class you want (necromancer, arcanist, warden, which are/were DLC, require the DLC to subclass into)
If you already have a character that's fully leveled and of the class you want to subclass into (you're a sorc and have a templar alt, and want to subclass templar), you just have to level the skills. If you don't have a character of that class (never leveled a templar), you can do a quest to unlock leveling for that subclass, rather than needing to fully level an alt to unlock that subclass.
You must keep at least one skill line from your base class
You can only take one skill line from a specific class (ie you can be a warden at base, and take a templar and dragonknight skill line, but not 2 templar skill lines)
Passives work as stated. If they buff only skills from that skill line, then that's how it works. If it says it buffs class skills in general, it includes All class skills.
Class mastery scripts and infinite archive sets are set to your base class
The armory saves your selections
You can swap skill lines in the standard respec shrine/scroll method
